CAR-COUPLING.

Speeieaton of Letters Patent.

Patented Oct. 22, 1907.

Application filed February 2,1907. Serial No; 355,475.

To all whom it may concern:

Be it known that VI, WILHELM SCHURR, a subject of the Emperor ofGermany, residing at Cannstatt near Stuttgart, Wrtemberg, Germany, haveinvented certain new and useful Improvements in Car-Couplings; and I dohereby declare th e 'following to be a ull, clear, and exact descriptionoi the invention, such as will en able others skilled in the art towhich it appertains to make and use the same.

illy invention relates to a railway car coupling, which locksautomatically when two ears come together, and

which may be unlocked from the sides of the cars by a pull or bypressure.

My coupling consists principally in the combination of an actuatingmember in the form oi a hinged loop and a locking member in the form ofa pair of hinged arms normally held in a distended position and one oiwhich carries a freely swinging locking bar. I provide means locatedbetween said arms adapted to be operated by said actuating loop memberto draw said hinged arms toward one another and to thrust said freelyswing ing locking bar through said looped member and the opposite hingedmember to securely hold the cars together.

The accompanying drawing shows my invention in Figures l to ll, of whichFig. l is an elevation partly in section o the device in a coupledposition; Fig. 2 is a plan view partly in section o the same; Fig. 3 isan elevation partly in section of the hinged arm locking member in thedistended or unlocked position; Fig. 4 is an elevation of the saine inthe closed position; Fig. 5 is a plan View of the same; Fig. 6 is alongitudinal section through a portion of the locking member and showingthe latch mechanism operated by a chain; Fig. 7 is a transverse sectionot same; Fig. 8 is apart sectional view of a modi iisd form showing thelatch operated by pressure on a foot piece; Fig. 9 is a plan view ofsame; Fig. l0 is a plan view of the hinged loop actuating member; andFig. Il is a side view osaine and broken away.

Referring to the iigurcs, A and A represent the loop actuating membershinged at the ends E, E, to the car through eyes F, by means oi" thebolts G, G. Loop members A., Af, are also provided at their ends withstops II, II, adapted to limit the swing ofthe same.

The locking member comprises the arms L, IJ, hinged at N to the sleeveIC. Sleeve K is mounted on the extremity of the draw bar .l oi the car.

M is the free swinging locking bar hinged at B to the arms l'/ andadapted to lie behind the transverse bar C when in the closed position.

O is the trip bar slidably mounted in the sleeve K between hinged armsL, L, and provided with trip arms Q, Q, hinged at the outer end thereof.The trip arms Q, Q, are pivotally connected at their other endsintermediate oi the hinged arms L, L, whereby when said trip bar O isforced inward from the pressure of the opposing loop member A, thehinged arms L, L, will be drawn toward one another.

P is a spring operating within the sleeve K between the end oi the drawbar J and the trip bar O and operating to force said trip bar outward.

The trip bar O is provided with a recess O/ into which a latch pin R isadapted to be projected by means Oi a spring IV. Latch pin R is mountedthrough a sup'- porting 'frame R2 and through an opening in the Wall ofthe sleeve K.

As shown in Figs. 6 and 7 the latch pin R is pulled out to release tripbar O by means of a chain D running to the side ofthe car as shown inFig. 2, but I may with equal effectiveness provide the operating meansshown in Figs. 8 and 9, in which the lever S is loosely mounted at oneend through a slot in the shank of the latch pin R and is rigidlymounted on the shaft V at its other end.4 A foot lever 'l is mounted onshaft U at the side of the car, and said shaft will be oscillated by apressure thereon to pull the latch pin out as will be readily seen.

Having thus described my invention, what I claim l. ln a car coupling,the combination with a locking member comprising` a body portion andhinged arms connected to the body portion and normally held in adistended position, of a tripping mechanism mounted within said lockingmember and pivotally connected to said hinged arms, and means foractuating said tripping mechanism to draw said hinged arms toward oneanother, substantially as described.

2. In a car coupling, the combination with'a locking member comprising ahollow body portion mounted on the draw bar, hinged arms extending fromsaid body portion and normally held in a distended position, of a tripbar mounted in the hollow of said body portion, pivotal connectionsarranged between said bar and said hing'cdarms whereby, when said tripbar is pushed inward, said hinged arms will be drawn together, one ofsaid hinged arms being provided with a transverse bar and a locking barcarried by the other of said arms and adapted to lay behind saidtransverse bar when in the locked position, substantially as described.

3. In a car coupling, the combination with a locking member comprising ahollow body portion, hinged arms extending from said body portion andnormally held in a distended position, of a trip bar mounted in thehollow of said body portion, trip arms connecting said bar to saidhinged arms, said bar beine; adapted to be pressed inward to draw saidhinged arms together and being provided with a recess therein, and alatch mechanism mounted through the wall of said body portion andadapted to e11- gage within said recess when said trip bar is pushedinward, substantially as described.

4. In a ear coupling, the combination with a locking member comprising ahollow body portion, hinged arms extending from said body portion andnormally held in a distended position, of a trip bar mounted in thehollow of said body portion, trip arms connecting' said bar to saidhinged arms, said bar being adapted to be pressed i11- ward to draw saidhinged arms together, and being provided with a recess therein, a springpressed latch mounted through the wall of said hollow body portion andadapted to engage within said recess when said trip bar is pulledinward, and means whereby said latch may be 1 released from the side ofthe car, substantially as described.

In testimony whereof, I ax my signature, in presence of two witnesses.
